BACKGROUND INVENTOR. HENRY J. WALTER i atented Jan. I, 1963 3,070315 SLIDE TITLE MEANS Henry J. Walter, Bethpage, N.Y., assignor to Viewlex, Ind, Hoibrook, N.Y. Filed (let. 3, 1961, $81. No. 142,612 4 Claims. (Cl. 40-458) This invention relates to means for applying titles or descriptive material on film slides or strip film.

More particularly the invention relates to new and improved means for applying titles or descriptive material so that the titles or descriptive material may be projected, either with the slide or film or as a separate frame in strip film.

It is rather difiicult for the average person to insert or apply projectable titles or other information on slides or film. One of the ways to do this is to print the Written material on a card and then photograph it. However, this procedure is too elaborate and expensive for the ordinary amateur photographer.

The present invention provides means for inserting projectable written information on slide mounts or in strip film. For the slide mounts, a hole is punched in the cardboard mounting and a snap-in cup of plastic having a pigmented surface is snapped into the holes. The written information is then applied to the pigmented cup by scratching off the pigment with a sharp point for instance a phonograph needle mounted in a pen holder. It is desirable to make the writing small as the size is magnified many times by the projection. The size of the writing or printing may be reduced by means of a pantograph device such as disclosed in co-pending application S.N. 841,236, filed September 21, 1959, for Methods and Apparatus for Titling Projection Slides.

In the case of strip film where it is desired to insert one or more entire frames of descriptive material, the present invention provides a pre-perforated length of the pigmented colloid plastic. The strip film is cut at the proper place and the frame having the written material on the pigmented colloid is inserted in the film by conventional methods.

Accordingly, a principal object of the invention is to provide new and improved film title means.

Another object of the invention is to provide new and improved title means for projection slides.

Another object of the invention is to provide new and improved means and methods for inserting titles or other written information on a strip film, or slide.

Another object of the present invention is to provide new and improved slide mounts.

Another object of the invention is to provide new and improved means for inserting written information on slide film mounts which information is adapted to be projected together with the slide comprising an aperture cut in the slide mount and a cup of pigmented plastic snapped into said aperture, the written material being applied to said pigmented or coated plastic by scratching the pigment off with a sharp point.

These and other objects of the invention will be apparent in the following specification and drawings of which:

FIG. 1 is a plan view of a projection slide embodiment of the present invention.

FIG. 2 is a side view of FIG. 1.

FIG. 3 is an enlarged plan view of the snap-in cup of the present invention.

FIG. 4 is a side view of FIG. 3.

FIG. 5 is a sectional view of the snap-in cup of FIG. 4.

FIG. 6 is an enlarged sectional view of a modified cup.

FIG. 7 is a plan view of an embodiment of the present invention applied to strip film.

FIG. 8 is a side view of FIG. 6.

Referring to the figures, there is shown a conventional slide mount 1 which is generally of cardboard having an aperture 2 in which is mounted a film slide 3 in conventional manner.

In order to apply the title or written information to the slide in such manner that the information will be projected, an aperture 4 is punched out of the mount. The aperture 4 is within the light path of a conventional projector. A plastic cup 5 of transparent plastic having an opaque pigmented coating is inserted in the aperture 4. Cup 5 has a pair of projecting beads 6 and 7 along two of its lower edges which are adapted to project under or against the edges of the aperture 4 to hold the cup in place. The other side of the cup is held by the projecting lips 8 and 9. The plastic cup has sufficient flexibility to permit the insertion of the heads 6 and 7 through the aperture 4. The material used for the cup may be a conventional pigmented colloid of the type which is used for making master negatives and for map making. This material is commercially available from suppliers of such equipment. This material is a conventional transparent plastic having an opaque coating and is easily removable by scratching or scribing with a sharp point for instance a phonograph needle mounted in a pen holder. The writing or printing is preferably done with a pantograph attachment such as disclosed in the above mentioned co-pending patent application in order to reduce the size.

The cup 5 is preferably formed with a suitable die. The depth of the cup must be such that the writing surface 5 is in the plane of the slide so that the writing will be properly focused.

FIG. 6 shows another embodiment of the cup which eliminates the beads. In this arrangement the cup 5 is lanced or punched along portions of two opposite sides to provide a pair of extending flaps 15 and 16 which are adapted to fit under or against the edges of the slide mount 1. Projecting flaps on two opposite sides of the cup are sufficient to hold the cup securely on the mount. However, portions of all four sides may be lanced if desired.

The cup may be snapped into the aperture of the slide mounting with slight finger pressure. The dimensions of the cup insure that the writing surface will be in the plane of the slide. This device simplifies the applying of Written information to slide mounts and makes it possible for the amateur photographer to have a simple reliable method for labeling the mounts.

Another way to incorporate the information is to remove part of the emulsion on the film itself on an opaque portion thereof. This may also be done by scratching with a sharp point or a phonograph needle.

FIGS. 7 and 8 show another modification of the invention wherein an entire frame containing written information is inserted in a strip film. In order to do this a pre-perforated piece 10 of the pigmented colloid slightly larger in size than one frame is cemented onto the film strip 11 by conventional cementing or other film editing techniques. The written information or explanatory material is applied to the transparent plastic by scratching off portions of the opaque coating 12 thereon with a sharp point as described above. The pigmented or coated frame is preferably inserted in the film first to permit easier handling. in the showing of the printing in FIG. 6 it is to be understood that the background is opaque and the letters are formed by scribing off the opaque coating. A pantograph engraving device may be used to reduce the size of the writing.

Therefore, the present invention provides simple and economical means and methods for applying titles or explanatory material to film slides or strip film. No

elaborate apparatus is required, and the process may be performed quickly and easily. The present device is particularly advantageous for teachers or lecturers preparing exhibits and slides or strip film for illustrated lectures.

Many modifications may be made by those desiring to practice the invention. For instance, if the explanatory material is lengthy, an entire slide may be made up of the pigmented colloid. Various other advantages and modifications of the device and process will occur to those having particular problems without departing from the scope and invention which i defined by the following claims.

I claim:

*1. Film title means comprising a slide film mounting, an aperture in said mounting within the area of light transmission, a transparent plastic sheet having a depression adapted to fit into said aperture and having an opaque coating, said depression having a pair of beads along at least two sides of said depression bottom said beads being adapted to extend against the lip of said aperture in said slide mount so that said depression may be snapped into said aperture.

2. Slide identification means comprising a trough of transparent plastic having an opaque coating, said trough having a pair of extending lips along its upper portion and having a pair of beaded portions along its lower edges, said trough being flexible enough to snap into an aperture slightly smaller than said beaded portions in a slide mount so that said beads will hold said trough in place in said slide mount.

3. Film title means comprising a slide film mounting, an aperture in said mounting within the area of light transmission, a transparent plastic sheet having an opaque coating and having a hollow oblong depression portion inserted in said aperture, said depression portion having a pair of punched portions along at least two sides of said depression portion forming flaps adapted to extend against the lip of said aperture in said slide mount so that said depression portion may be snapped into said aperture.

4. Slide identification means comprising a sheet of transparent plastic having an opaque coating and having a hollow oblong epressed portion, said depressed portion having a pair of extending lips along its upper portion and having a pair of extruding flap portions along its lower sides, said depressed portion being flexible enough to snap into an aperture slightly smaller than said flap portions in a slide mount so that said flaps will hold said depressed portion in place in said slide mount.
